Beit known that' l, ANTHONY Filmen, seiti- Zen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Temporary Binders, of which the following is a fu l, clear, and exact specilieation.

My invention relates to thatclass of temporary binders usually comprising two hack members or covers having hinged sections in one of which impaIing-pins are secured and pass through the other which is provided with grips or clamps for holdin seid other section in place on the pins; an my invention has for its primary object to provide an improved and sim le form of tern orar binder capable of eing mani ulated) Wit one hand, so that the same han may be emloyed for releasing the do s or grips and ifi-)1n the cover while the ot er hand is free for ot er use.

1With the described ends in view my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said object and certain other objects hereinafter appearing are attained, all as fully described wlth reference to the accompanying drawings, and

more particularly pointed out in the claims.Y

In the said drawings, Figure i is a plan proved temporary binder, and Fig. 2 .is a vertical transverse section thereof.

1 2 are theY top and bottoni covers, whichVVV Y 'n'rg 7, so as not to constitute an obj ectienable are respectively provided with the aforesaid ed sections 3 4, and in the bottom one of these sections are screwed or otherwise secured impe -pins 5, which pass loosely through the top ged seetion and upon which pins the leaves 6 may be impaled or withdrawn when the section 3, with its cover Lis 'lifted ol. Secured to the upper face of the section 3 and extending longitudinally thereof is a casing 7, whioluif desired, may be composed of thin sheet metal struck u in the form of an inverted box and fastene to the section 3 by means of screws 8 or other suitable devices, and through thisV casing 7 the pins 5 also pass. 9 10 are gripping-do s which are provided in their upper ends wi't V-'sha ed notches 11V or notches of other suitable l) embracing and gri ping the pins 5 respectively, and lthese ogs are so arranged that erm partially they do not prevent the section 3 from being pushed downwardly on the pins 5, but upward movement of such section is restricted by the direct thrust of the dogs against the pins. To this end the dogs are mounted upon horizontal pivot-pins 12, which are located considerably below the point of their engagement with the pins, and consequently While the dog may be readily deliected in an upward direction yas the section 3 is pushed downwardly any upward movementcf Vthe section results in forcing the notched end of the dog directly against and substantially transversely of the impaling-pin. The npper side of the easing 7 is provided with apertures 13, through which the dogs-9 10 project, respectively, and the lower ends of the dogs are formed with levers 14 15, under which are interposed leaf-springs i@ 1? or springs of an suitable form, secured directly to the top oV the section 3, so as to lift the contiguous ends of the levers 14 and thereby keep the 4dogs 9 10 in rm engagement with the impaling-pins. Arranged to lbear upon the upper end of each of the levers 14 15 isan o erating-lever 18, which is su ported within t e casing 7 near its lower en on a horizontal pivot 19 and pro'ects through an aperture 2O in the top of t e casing, where it may be given a slig Y at i8, to facilitate the engagement of the thumb or finger therewith. lire extremity of the downwardly-curved portion 18m may with or below the-surface of Vthe casprojection, and in order that the finger or thumbof the operator ma 4readily engage with it the easing is formedY with a countersinlrl' et e Ypoint below this curved end.

The operating-levers 18 are located, i referabiy, e uidistant from the center o the binder an at a distance apart convenient to the thumb' and finger of one hand, so that the operator may grasp both levers at one time and by ressmg the fingers toward each other the endg of the levers will be slightly raised, which wiil depress their free ends and simultaneously release the dogs 9 10 from engagement with the inapelng-pins, thereby enabling the operator to release the dogs and lt'the cover by one and the same hand and at the same time and to again lock o r the section 3 in place by simply releasing his hold upon the levers 18 and pressing downht downward curve, as shown zoo wardly upon said section. It will also be seen t iat the operatmg-levers have comparatively short arms bearing against the comparatively long arms of the levers 1.4 1.5, thereby constituting very powerful compound levers for releasing the dogs and rendering this one-hand operation feasible and convenient, while at the same time by giving the springs 16 17 a bearing against the eX- treme outer ends of the long levers 14 15 I am enabled to employ flat and comparatively weak springs for producing the requisite pressure against the impaling-pins, and consequently=the mechanism may be compact and neat and located within the casing 7.

Having thus described my invention7 what I claim as new therein, and desire to secure by Letters Patent, is-

1. In a temporary binder, the combination with the two covers and the impaling-pins secured to one and projecting through the other, of two gripping-dogs arranged between the impalingbins, on said latter cover, and engaging with said pins 'for holding the covers against relative movement on the pins, pivoted levers by which said dogs are supported and operated, and independent operating-levers arranged between the pins and accesible simultaneously to one hand of the o erator, and impinging the aforesaid levers lior oscillating the latter and releasing said dogs.

2. In a temporary binder, the combination with the top and bottom covers and the impalingins secured to one and passing throng 1 the other, of gripping-dogs mounted upon the top cover and engaging said pins for holding the to cover against movement thereon, elongate levers projecting toward each other for supporting and operating said dogs, and independent operating-levers arranged between said ins and accessible simultaneously to one and of the operator, and having short arms engaging said elongated levers for releasing said dogs, the upper ends of said operating-levers being turned downwardly to form a handle or lift wherewith to raise said top cover when the dogs are released.

3. In a temporary binder, the combination with the top and bottom covers and the impalingins secured to one and passing throng the other, gripping-dogs impinging said pins and extending downwardly therefrom toward each other, pivots u )on which said dogs are sup. orted respectively, located at points below the loint of engagement between the pins an( the dogs, springs for pressing said dogs into contact with the pins, and independent operating-levers arranged upon said top cover for releasing said dogs.

4. In a temporary binder, the cmnbination with the top and bottom covers and the impaling-pins secured to one and )assing through the other, of a casing secure to the top cover and through which said pins pass, said casing having apertures and countersinks adjacent to said apertures, gripping-h dogs pivoted within said casing and engaging said pins respectively, and operating-levers pivoted withm said casing for releasing said dogs and projecting through said apertures and over said countersinks respectively.

5. In a temporary binder, the combination with the top and bottom covers and the impaling-pins secured in one and passing through the other, of pivoted dogs secured to the top cover and having elongated levers, flat springs secured under said levers and bearing upwardly against the free ends thereof and pivoted inde endent operating-levers bearing upon said rst levers for depressing them against the resistance of said springs.

6. In a temporary binder, the combination with a top and bottom cover, and impalingpins carried by one cover and assin'g through the other, of a casing secure to the top cover and through which the pins pass, gri ping-dogs pivoted within the casing7 one en of said dogs projecting through the casing and dis osed to engage the pins, levers pivoted wit in the casing, with one end engaging the other end of the dogs, the other end of the levers projecting through the casing and bent to form handles, and springs secured to the cover within the casing and engaging the dogs adjacent the point of contact of the levers therewith, the free ends of the levers being adapted to be raised to depress the other ends to overcome the pressure of the springs and release the dogs.
